4m - 3n = 8
Add 3n to both sides.
4m = 3n + 8
Divide both sides by 4.
m = 3/4n + 2
So, m = 3/4n + 2
However, if you made a typo, and meant 3m instead of 3n, your answer would be :
4m - 3n = 8
n = 8

Let the unknown number be x.
x × -7 = 7 (x + -40)
-7x = 7x - 280
-14x = -280
x = 280/14
x = 20
Hope this helps!
So we see that the ratio between the two octagons is 7:1, since 28/4=7 so what we do next is multiply the values of the smaller octagon by 7. But that’s the long way. There’s actually a shortcut by multiplying the perimeter of the smaller octagon, 34, by 7. This in turn equals 238.
1) find slope. when its perpendicular, It will be a negative reciprocal to the given slope so m1= -1/m1
m=-1
2)
y =-1x+b
(-3)=-1(2)+b
-3=-2+b
b=-1
3) y=-1x-1
hope I helped!
